Input Change Notification Module

The input change notification module provides the

dsPIC30F devices the ability to generate interrupt

requests to the processor in response to a change-of-

state on selected input pins. This module is capable of

detecting input change-of-states, even in Sleep mode

when the clocks are disabled. There are 22 external

signals (CN0 through CN21) for dsPIC30F6010A and

external

signals

(CN0

through

CN19)

for

dsPIC30F6015 that may be selected (enabled) for

generating an interrupt request on a change-of-state.

Please refer to the Pin Diagrams for CN pin locations.
